Abstract: A server receives a certificate signing request and onboarding information for an applicant device, and identifies a customer associated with the applicant device based on an applicant device identifier and a database identifiers associated with customers. The device determines a registered device associated with the customer is a trusted device, a location trust value for the applicant device based on a geolocation proximity between the applicant device and the trusted device, and an environment trust value for the applicant device based on a proximity in a network topology between the applicant device and the trusted device. The device further determines a trust score for the applicant device based on the location trust value and the environment trust value, and sends a signed certificate to the applicant device over the network when the trust score for the applicant device exceeds a threshold.

Abstract: In one embodiment, a supervisory device in a network receives from a plurality of access points (APs) in the network data regarding a network availability request broadcast by a node seeking to access the network and received by the APs in the plurality. The supervisory device uniquely associates the node with a virtual access point (VAP) for the node and forms a VAP mapping between the VAP for the node and a set of the APs in the plurality selected based on the received data regarding the network availability request. One of the APs in the mapping is designated as a primary access point for the node. The supervisory device instructs the primary AP to send a network availability response to the node that includes information for the VAP. The node uses the information for the VAP to access the network via the set of APs in the VAP mapping.

Abstract: Techniques are provided for converting a node-locked licensing scheme to a cloud-based management of licenses to use computer products. In one example, a license manager device of a vendor receives a request to upgrade a computer product that is associated with a node-locked certificate that configures the computer product to be node-locked to a particular device. The request includes an identifier of the computer product. The license manager device registers the product identifier to a license pool of a customer account associated with the computer product. The license pool includes entitlements to use the computer product. The license manager device searches for node-locked entitlements that are associated with the node-locked certificate. The license manager device moves the node-locked entitlements to the license pool.

Abstract: Techniques are provided herein for establishing at a network management server a presence on a network. A presence associated with one or more managed devices on the network is detected. An instant messaging (IM) session is established with the one or more managed devices. The IM session forms a virtual chat room for performing a management function on the one or more managed devices, and IM messages are sent that are configured to perform the management function on the one or more managed devices. Techniques are also provided herein for establishing on a network an enriched presence by a network management server that is configured to perform a management function via a presence function of a messaging and presence protocol.

Abstract: In one embodiment, upstream transmission throughput in a cable network is markedly increased by moving up the US/DS frequency split by approximately an order of magnitude to a few hundred MHz. Additional transceivers (carriers) may be implemented to take advantage of the broader spectrum. A block of multiple upstream carriers (FIG. 2A) are associated to form a single logical upstream providing a high-bandwidth, in-order packet stream. The carriers have a common start time (704), pursuant to a single MAP message, and operation synchronously to transmit an upstream transmission frame (250). They may use OFDM or discrete carriers. A convergence layer (350) assembles the data from all of the upstream channels (320,322,324) for presentation to the MAC layer logic (308,310) as a single, serial, high-speed transmission from the CM.

Abstract: A system and method for determining the characteristics of a device coupled to a client device are disclosed. A method, according to one embodiment, includes driving a display device with a first video output signal formatted according to a first video interface specification; responsive to driving the display device, soliciting user input based on information included in the first video output signal; determining a characteristic of the display device based on the user input; and driving the display device according to the determined characteristic.

Abstract: In an example embodiment, an apparatus comprising a physical layer processing device that comprises logic configured to process a packet received from a physical layer interface is disclosed. The physical layer processing device logic is further configured to determine a preamble portion of the packet and a data portion of the packet. The physical layer processing device logic is further configured to insert a timestamp into the preamble portion of the packet. The physical layer processing device logic forwards the packet with the timestamp inserted into the preamble.

Abstract: A method for a computer server includes receiving search criteria from a first user at a remote client, receiving a first identifier associated with the first user, performing a search to determine a plurality of search results including a first and a second search result, determining a first rating from a second user associated with the first search result, determining a first social network indicia from the second user to the first user within a social network, determining a second rating from a third user associated with the second search result, determining a second social network indicia from the third user to the first user within the social network, providing the first search result to the remote client including the first rating and the first social network indicia, and providing the second search result to the remote client including the second rating and the second social network indicia.

Abstract: In one example, a Cable Modem Termination System (CMTS) determines target Radio Frequency (RF) bandwidth amounts for Data Over Cable System Interface Specification (DOCSIS) bonding groups according to the DOCSIS priority of active flows within the bonding groups. The CMTS then tunes bandwidth allocation amongst the DOCSIS bonding groups according to the target bandwidth amounts. The target bandwidth amounts can be recalculated at intervals, and the bandwidth allocation re-tuned at the intervals, to account for changes in flow activity or DOCSIS priority assignment.

Abstract: LDP label switching may be discontinued gracefully on one or more selected ones of multiple links interconnecting a pair of label switched routers (LSRs) while leaving label switching in operation on the remaining LDP-enabled links. Mechanisms for graceful shutdown of LDP on a selected link are added by way of modification to one or more of: e.g., LDP discovery Hello messages, LDP Label Withdraw/Label Release messages, LDP Notification messages.

Abstract: Transitions among different upstream frequency channels in a cable television plant in order to transmit data occur while considering the noise level of the upstream frequency channel presently being used to transmit data. By taking into account the noise level of the presently used upstream frequency channel, the CMTS in a cable plant can make a more intelligent decision as to whether it is worthwhile changing the upstream frequency channel for a group of cable modems. A spectrum analyzer determines the noise level of a presently used frequency channel. A bit error rate for the present frequency channel is detected. The spectrum analyzer then determines whether the bit error rate exceeds a threshold value. Is so, it is then determined whether the noise level of the present frequency channel is greater than or less than the noise level of another frequency channel having the lowest noise level plus a buffer noise value.
